WINDOWfSCREEN ROLLER.

SPECIFICATION forming part of Letters Patent No. 311,044, dated January20, 1885.

Application filed July .25, [834.

T0 ail whmn, it may concern..-

Be it known that I, SIMEoN U. TARNEY, a citizen of the United States,residing at Auburn, in the county of De Kalb and State of Indiana, haveinvented certain new and useful Improvements in Window-Screen Rollers,of which the following is a specification,reference being had therein tothe accompanying drawings.

The object of my invention is to provide a window-screen roller whichcan be readily attached by any person to windows of different widths,convenient to put in or take out at pleasure, can be rigidly kept inplace, the screen can be drawn or stretched perfectly taut and smooth atboth edges and the center, can be compactly packed, without taking topieces, when temporarily out of use, or for storing or shipping, anddurable and economical. These objects I attain by means of a concaveroller having a groove, a tightening or stretching device connected witha wooden strip by metallic angle-shaped metal attachments having beveledvertical slots for ready adjustment at one side of the window-frame, anda wooden strip having metallic attach ment-pieces provided with angularslots and flat ears for ready and perfect attachment to the other sideof the window-frame.

In the accompanying drawings, which form a part of this specification,Figure l is a front elevation showing my inventionwith screen attachedas applied; Fig. 2, a detail detached view of the upper end of theconcave roller, showing the groove, the tightening device, and strip forattachment to one side of the window-frame, and the upperend showing onemetal attachment-piece with angular slot and flat ear of the strip forattachment to the other side; Fig. 3, a plan View of the tighteningdevice; and Fig. 4, a detail section through line w as, Fig. 3, showingthe beveled vertical slot. Y

Similar letters of reference indicate like parts.

A A represent the window-frame; a a, the strips that hold the screen Bin position 5 0, the concave roller, having parallel groove 0,- D, thetop ratchet-gear; d, the hand-lever, with projection d, by which toengage with the teeth of the top ratchet-gear to turn the (X0 model.)

concave roller in order to stretch the screen, which is retained in itsplace by the pawl E. A metal attachment-piece, F, of angular shape,provided with a shoulder, to which the pawl E is loosely riveted at r,and having a beveled vertical slot, f, is rigidly secured to the side ofthe wooden strip a near the top, by means of common wood-screws. Asimilar metal attachment-piece, but without ashoulder, is in like mannersecured to the side of said strip, near the other end. The topratchet-gear, l), is rigidly secured to the top end of the concaveroller 0 by means of common woodscrews, and it is provided with ahub, h,which is employed to hold the concave rollerin place by passing itthrough a hole in the metal attachment-piece F, and it further serves asmeans for securing the hand-1ever d, to which it is loosely fitted andretained in its proper place by pin 19. The lower end of the concaveroller 0 rests on the lower metal attachment, as shown in Fig. 1. ment,G, having an angular slot, 9, anda fiat ear, is rigidly secured bycommon woodscrews on the edge, near the top end, of strip a. A similarmetal attachment is secured in like manner on the edge near the lowerend. (N 0t specially shown in drawings.) Pawl E is provided with aprojection, E, back of rivet r, for the purpose of enabling aperson withone hand to disengage the pawl from the ratchet when desired.

In order to take the screen from the window,the ratchet must be turned alittle to the right by lever d, and at the same time bypressing on theprojection E with thumb or finger the pawl is liberated and thrown to avertical position, where it remains until the screen is removed from thewindow, the weight of the projection E being sufficient to balance orretain it in said vertical position.

In applying my invention netting or screen cloth of any material, eitherof fabric or metal, may be taken and cut to about the desired length,one end of which is then tacked onto the flat side of the strip a, andthe other end to the parallel angular bevelcin the concave roller 0. Twocommon wood-screws are driveninto either side of awindow-frame untiltheir heads protrude about half an inch. The roller attachments andscreen are taken up, the open- A metal attach-- ing of the angular slotis slipped in by the The strip a is now placed on the screws in theother side of the window-frame by means of the hole 0, and slightlyforced down. The heads of the screws snugly fitting the beveled verticalslotsf, that part is firmly secured in place. The screen-cloth now hangsloose, but by pulling the hand-lever. d toward you the concave roller isturned, the screen cloth wound around it, and all the slack taken up andheld by the pawl E, which drops in and engages with the teeth on the topratchet-gear, D, thus preventing the screen from u n rolling when thehand-lever is released. Vhen the screen is not needed in the window, itcan be taken out by first disengagingthe pawl, which loosens thescreeircloth, and then by lilting up the strips, which releases themfrom the screw-heads in-the window-frames.

There being no frame to the top or bottom of the screen, when myinvention is used, it can be seen that the whole appliance can be rolledinto a very small compass.

\Vith my concave roller one is enabled to stretch the screen-cloth atboth edges and the center and have all taut, and, so far as I have beenable to learn, this is the only roller that will stretch a screen sothat it will not sag in the center or at the edges within a short time,and by having the groove the screencloth is fitted to the concave rollerin such a manner that it rolls up perfectly smooth.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination of the strip a, the screen, the concave roller 0,having ratchet D, hearing F, and pawl, substantially as described.

2. The screen and roller, the. lever cl, having a lip or projection, d,in combination with ratchet D, bearing F, having shoulder at rightangles to its main portion, the pawl E, having the projection 15,pivoted to said shoulder, and the hub h, substantially as described.

3. The combination of the concave roller C, the lever (I, provided witha catching projection, d, integral therewith, the ratchet D,

pawl E, having the projection E, and hub h, substantially as describedand specified, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
